The (British) Royal Society has made the Proceedings of the Royal Society (Mathematical, Physical & Engineering Sciences) available to read and download for free to celebrate its 350th anniversary. This offer is good through February 28th. After that, the pay wall goes back up.

The papers go back to the time of Isaac Newton. As just one example, if you've struggled with applications of Maxwell's equations, the following paper is where it all started:

A Dynamical Theory of the Electromagnetic Field J. Clerk Maxwell, Proc R. Soc. Lond. 1863 vol. 13 531-6

The first announcement of Maxwell's discovery that light, electricity and magnetism can be understood in a single framework, underlying radio, television, and our whole communications technology.

According to the site, there are about 65,000 papers available. If you're interested, go to the following URL:
